It's 1820s Edinburgh. Since losing their parents, Kate and Andrew have been living with their cold-hearted aunt and uncle within the vaults of the city's South Bridge. Worked relentlessly by day and tormented at night, Kate has little chance to dream of the future until the day Richard Hope walks into her life. Wealthy, upper-class and studying to become a doctor, Richard knows that he and Kate come from very different worlds, but as soon as he lays eyes upon her, he knows she is the girl for him. Instantly smitten, Richard vows to do whatever it takes to spend his time with her. Set against a richly evoked historical background, One Sweet Moment beautifully captures the struggle of young love to survive against all odds.
